【摘要】：随着中国城市建设的发展，，城镇化速度正在飞速进行，随之而来的城镇交通基础建设的承载量越发的难以满足日益增长的城市居民数量，引发了城市交通拥堵，出行困难等现象。但是，随着近年来智能交通技术的进步，利用计算机互联网技术在交通服务领域逐步实现了公交信息化系统。人们希望通过对公交车辆信息的精准定位，实现对公交线路的有效管理，完善对公交车辆的调度，增加交通基础设施的使用效率。如今，无线通讯网络，地理信息系统不断发展，研究地理信息平台上的车辆位置信息快速加载具有十分重要的意义。 本文通过运用SSH、JCS等开源技术来实现实时的公交网络GIS系统，并通过对不同定位方法和信息加载过程的分析和比较，对车辆定位和位置的加载过程进行优化，运用基于位置服务的思想对公交车辆进行实时位置加载和管理，分析、设计与实现了基于SOA的后台数据支撑服务平台GIS系统。同时选取Memcache等技术来搭建缓存服务器用以解决高并发访问等性能瓶颈问题。与此同时，移动端选择Android移动平台进行了深度软件定制与开发工作，设计并实现了基于Android的高度符合SOA服务思想的GIS移动平台软件。通过移动端与后台的交互配合，结合多种类，多功能，多服务的软件体系，最终实现在多平台下的移动软件的车辆搜索、查询、定位功能。对公交车辆、线路、站点进行统一管理。
[Abstract]:With the development of urban construction in China, the speed of urbanization is proceeding rapidly, and the carrying capacity of urban traffic infrastructure is becoming more and more difficult to meet the increasing number of urban residents, causing urban traffic congestion. Travel difficulties, etc. However, with the progress of intelligent transportation technology in recent years, the use of computer Internet technology in the field of transportation services has gradually realized the information system of public transportation. People hope to achieve the effective management of public transport lines, improve the scheduling of public transport vehicles, and increase the efficiency of traffic infrastructure through the accurate positioning of public transport vehicle information. Nowadays, with the development of wireless communication network and geographic information system, it is very important to study the rapid loading of vehicle position information on geographic information platform. In this paper, we use the open source technology such as GIS to realize the real-time public transport network GIS system, and through the analysis and comparison of different positioning methods and information loading process, we optimize the vehicle location and location loading process. Based on the idea of location-based service, the real-time location loading and management of public transport vehicles is carried out, and the GIS system of backstage data support service platform based on SOA is designed and implemented. At the same time, Memcache and other technologies are selected to build cache server to solve the performance bottleneck of high concurrent access. At the same time, the mobile side chooses the Android mobile platform to carry on the deep software customization and the development work, designs and implements the GIS mobile platform software based on the Android highly conforms to the SOA service idea. Through the interaction between the mobile end and the background, combined with the multi-type, multi-function and multi-service software architecture, the vehicle search, query and location functions of the mobile software under the multi-platform are finally realized. Unified management of bus vehicles, routes and stations.
